This Japanese Denso company is a subsidiary of Toyota Denso. In order to realize the electronic development of 1997 Kanban management system, a two-dimensional code with a larger capacity than bar code has been developed, which is what we are familiar with now.
Denso does not monopolize this technology, not only Toyota, but also has its own strategy to promote QR code. Now it is a software that makes QR codes for free in the whole society, but only the scanners that sell QR codes are kept.
Nowadays, in Japan, QR code scanners and QR codes are widely used by local chain convenience store enterprises. But it has not been widely promoted overseas.
Time goes back to 20 10. At that time, mobile payment in China also had its own code, but due to security problems, Japanese QR code technology was finally adopted.
This is because the QR code has an advantage in security, and Denso Corporation of Japan discloses related technologies free of charge, and does not charge patent fees. If the Japanese Denso Company charged the corresponding fees like Microsoft in the United States, the QR code would not be popularized so quickly in China.
Because Microsoft in the United States is now similar to the coding of two-dimensional code, patent protection is charged, so it has not been popularized so far.
Someone once told the director of Denso that a QR code is 10 cent. Now, Denso's income in China is very valuable.
However, the person in charge of the company said that he had no regrets about the original decision. It is precisely because of the free and open technology that QR codes can be popularized all over the world.
